That's all from me for tonight ladies and gentlemen. Thank you very much for joining me! What an outstanding performance we witnessed from Borussia Dortmund. The odds on an all-German Champions League final will have just plummeted! Good night!

FULL-TIME: DORTMUND 4-1 MADRID Klopp masterminded a stunning victory tonight, as his side stunned Mourinho's men to take a resounding 4-1 lead going into the second leg of their Champions League semi-final. Lewandowski was the star for the hosts, as he scored four fine goals in a superb individual performance. Ronaldo had made it 1-1 shortly before the break, but a second-half trio from Lewandowski put Dortmund in full control at the midway point in this tie.

90' + 4'

VARANE HAMMERS A SHOT JUST WIDE!! The French youngster has scored some crucial goals against Barcelona for Madrid this season, but on this occasion his strike is just off target. The corner fell to him invitingly inside the penalty area but his snap-shot effort with his left foot flew past Weidenfeller's right-hand post.

90' + 3'

However, they do now have a corner over on the left...

SubstitutionIlkay GündoganJulian Schieber

90' + 2'

A handball from Ramos gifts Dortmund a free kick just outside their own penalty area. The Spanish side are not helping themselves as they try and pull a goal back here, they have given away the ball cheaply and conceded a number of silly free kicks.

90' + 1'

Dortmund's last change is to bring on Julian Schieber for the very impressive Gundogan. The 22-year-old was brilliant in midfield for the home side tonight.

90'

The fourth official signals for four minutes of added time at the end of this game.

88'

VITAL BLOCK FROM WEIDENFELLER!! The Dortmund shot-stopper did very well to spread himself wide to stop Ronaldo from close range as the Madrid star stretched to make contact with Khedira's threaded through ball.

87'

Reus is in no hurry to take a Dortmund throw high on the left-hand side, and Madrid are barely even pressing him to get the ball back in play!

86'

Ronaldo gets the ball in space on the right but after cutting inside on to his left foot he is calmly dispossessed by Hummels on the edge of the box.

85'

A tired tackle from Ozil on Reus results in a free kick for Dortmund inside their own half. Madrid look leggy and at a loss as to how to get past the likes of Subotic and Hummels.

84'

That's not good enough from Di Maria. The left-footed winger has the ball on the wing but instead of finding his teammate with a pass as Madrid search for a goal he hammers the ball straight into the eager arms of Weidenfeller.

83'

SubstitutionJakub BlaszczykowskiSebastian Kehl

82'

Klopp takes the opportunity to waste some minutes by making some substitutions of his own as we head towards the final whistle. Sebastian Kehl has come on for Kuba and Kevin Grosskreutz has replaced Piszczek.

81'

For all Madrid's possession, they have had 58% of it tonight, they just haven't created enough goalscoring chances. And an efficient Bundesliga side have made them pay. It is just the same as Barcelona against Bayern last night.

80'

SubstitutionXabi AlonsoKaká

80'

Third change for Madrid as Kaka is introduced for Alonso. Can the Brazilian sprinkle some magic and help los Blancos pull a goal back late on here?

78'

LEWANDOWSKI NEARLY SCORES A FIFTH! The in-form forward curls a fine effort towards the top right corner from 20 yards that Lopez is forced into diving at to palm over the bar for a corner.

77'

Reus receives a pass from Gotze on the left side of the Madrid box but the flag is up against the Germany international. That was a close call!

76'

STAT: Madrid's playmaker, Ozil, was born in Dortmund's Ruhr heartland and started his career at local rivals Schalke.

74'

A long searching ball from Alonso goes straight through to Weidenfeller as Madrid struggle to break through Dortmund's defence.

73'

This Dortmund performance is made all the more impressive by the fact that one of their best players announced he was leaving for their rivals. Klopp has done brilliantly to focus his players' minds for this tie.

71'

Two changes in quick succession for Madrid as Modric now makes way for Angel Di Maria. The Argentine became a father for the first time on Monday, but this will not be a good end to his week!

70'

Yellow CardRobert Lewandowski

70'

Dortmund's four-goal hero Lewandowski is booked for a cynical block on Ramos as Madrid tried to attack down the right wing.

69'

As if to answer that question Mourinho brings on Karim Benzema for Higuain. Let's see if he can have an impact in these last 20 odd minutes.

What do Madrid do now?? They are being outclassed just as much as Barcelona were by Bayern last night.

Penalty GoalRobert LewandowskiLEWANDOWSKI SCORES A FOURTH GOAL!! The 24-year-old smashes the spot-kick high into the back of the net to make it 4-1 to Dortmund.

66'

PENALTY TO DORTMUND!! Alonso goes flying into the back of Reus inside the Madrid box and the home side now have a chance to add a fourth goal!

65'

Madrid's No.10 takes the set piece himself but his curling pass is nodded behind for a corner by Subotic.

64'

Yellow CardMesut Özil

64'

Ozil finds his way into Kuipers' book after waving an imaginary card at the official following a foul on Alonso. That was silly from the former Werder Bremen midfielder.

62'

MARVELLOUS FROM GUNDOGAN! The midfielder embarks on a fantastic run through the heart of Madrid's defence and nearly finishes it with a brilliant rising finish into the top right corner, only for Lopez to fling his left arm out and tip the ball over the bar.

61'

I hope for Dortmund's sake those Lewandowski to Bayern rumours aren't true.

60'

Madrid are throwing players forward in search of another goal. They would happily go back to Spain with two away goals under their belt with the score at 3-2 to Dortmund.

58'

STAT: Lewandowski is the first player to score three goals in one game against Madrid in the history of the Champions League.

57'

The Westfalenstadion is rocking! Just like it was two weeks ago when Dortmund fought past the challenge of another Spanish side, Malaga.

55'

GoalRobert LewandowskiWHAT A HAT-TRICK FROM LEWANDOWSKI!! DORTMUND LEAD 3-1!! The Polish striker adds his third of the night with an unbelievable goal. He takes the ball on his left foot on the penalty spot before dragging it away from the attention of Alonso and Pepe and hammering it into the roof of the net with his right foot. A fine fine goal from the Dortmund forward!

54'

Yellow CardSami Khedira

54'

Reus wins the ball from Khedira just inside the Dortmund half but the Madrid midfielder immediately seeks retribution by clattering into the former Borussia Monchengladbach man and conceding a free kick.

52'

We've been shown a replay of Lewandowski's second and he was definitely onside. His first touch to control the ball was glorious, and his toe-poked finish past Lopez wasn't bad either.

51'

Madrid have lost their composure after going behind for the second time, and their passing is all over the place.

50'

AssistMarco Reus

50'

GoalRobert LewandowskiLEWANDOWSKI STRIKES AGAIN!! DORTMUND ARE BACK IN FRONT!! Madrid's defence was static there as Lewandowski received the ball with his back to goal inside the box. They were sure he was offside! The Dortmund striker didn't wait to see what the officials thought though, as he quickly turned and prodded the ball past Lopez at his near post to make it 2-1.

48'

Gotze wins a corner off the legs of Khedira on the left and the Dortmund fans don't quite know how to react! They are happy to have the corner but they clearly feel slighted by Gotze's future transfer to their rivals Bayern Munich.

47'

Ramos goes in high on Reus right in front of the dugouts and the Madrid captain is reprimanded by the referee for the challenge and Dortmund are awarded a free kick.

46'

We're back underway at the Westfalenstadion. Madrid were a bit late coming out of the changing rooms for the second half. Mind games from Mourinho, perhaps?

Right then guys and girls, how do you see this second half going? I'm predicting more goals, but apart from that I'm going to place myself on the fence. Who do you think will make the difference after the break?

STAT: Ronaldo scored in his sixth consecutive Champions League game when he drew Madrid level at the end of that first half.

@CalmAsEver has waded in on Twitter with his thoughts on the Reus penalty debate. "We need robot refs man." I would LOVE to see a robot referee, although I think it's a fair few years before we will see that type of officiating.

Before the match I hoped it would be explosive and it certainly hasn't disappointed! There have been plenty of talking points already in this first half. I want to hear your thoughts during this interval! Send them to me on Twitter @charliefscott or post them in the box to the right of this commentary.

HALF-TIME: DORTMUND 1-1 MADRID The teams go in level at the break after a contentious goal late in the half from Ronaldo cancelled out Lewandowski's opener. The home side thought they should have had a penalty for a foul by Varane on Reus just 40 seconds before Ronaldo made it 1-1. Lewandowski had earlier given Klopp's men the lead after connecting well with a divine cross from the wantaway attacker Gotze. The game then exploded to life in the 42nd minute when Reus had his penalty shout turned down, before Madrid went straight up the other end and equalised courtesy of a close-range finish from Ronaldo.

45'

And there is the half-time whistle! It's all square at the Westfalenstadion.

44'

Mr Kuipers is not making any friends here! Reus is clearly fouled on the halfway line but again the man in mauve fails to award a free kick.

43'

AssistGonzalo Higuaín

43'

GoalCristiano RonaldoRONALDO EQUALISES FOR MADRID! Seconds after Dortmund think they should have a penalty los Blancos are right back in it! Their Portuguese star draws them level with a simple finish into an empty net after being set up by a sliding pass from Higuain. The Argentine forward had pounced on a poor touch from Hummels to seize possession and play the ball across the Dortmund box to his teammate.

42'

DORTMUND WANT A PENALTY! Varane loses his footing as he tries to stop Reus inside the box but the referee waves play on! The home side are furious!

41'

VITAL BLOCK FROM SUBOTIC!! The Dortmund centre-back throws his body in front of Alonso's vicious long-range strike to stop it from reaching Weidenfeller's goal.

40'

Coentrao sprints to the byline to latch on to a pass from Ozil, but he is unable to find Higuain with his left-footed cross as Piszczek closes him down quickly.

39'

Madrid are being afforded so little time and space on the ball by Dortmund. It has been a very disciplined and energetic performance from Klopp's men so far. The question is, how long can they keep it up?

38'

Ronaldo is told to get to his feet by the referee Bjorn Kuipers after he falls to the floor under a challenge from Piszczek. The Madeira-born forward did not like that, not one bit.

37'

STAT: Madrid have won just once on 24 visits to Germany and crashed out of the Champions League to Bundesliga opposition at this stage last season.

35'

Hummels and Subotic have been colossal in the air for Dortmund in this first half. I can't recall Higuain or Ronaldo winning a header.

34'

Reus and Schmelzer are on different wavelengths as the former tries to play the latter in on the left side of the Madrid box but the ball goes out for a goal kick to the away side.

33'

Coentrao hacks the ball away under pressure from Lewandowski as Dortmund threaten again!

32'

VERY GOOD DEFENDING FROM HIGUAIN! REALLY! The Argentine forward hasn't been involved much in an attacking sense for Madrid but he has just helped his team out defensively by tracking the run of Kuba and dispossessing him inside his own penalty area.

31'

With just over half an hour gone the game has settled down slightly, and Madrid have started to see far more of the ball than they did in the opening 15 minutes. Dortmund look very dangerous on the counterattack through Lewandowski, Kuba, Gotze and Reus.

29'

The former Liverpool midfielder's effort is punched away comfortably by Weidenfeller though, as Ramos and Ronaldo fail to get close to meeting the cross.

28'

And now we have another Madrid free kick! Madrid's Portuguese duo of Ronaldo and Fabio Coentrao link well on the left before the latter is caught by Subotic and now Alonso has a third opportunity to send a cross into the Dortmund box.

27'

Just seconds later Madrid win a free kick in an identical position, but this time Alonso's cross has far too much on it and the ball goes out for a goal kick to Dortmund.

26'

Ronaldo wins a free kick on the left wing after being caught by a late challenge from Lukasz Piszczek but Alonso's curling set piece is headed away by Hummels on the penalty spot.

25'

GOOD DEFENDING FROM MARCEL SCHMELZER! The Dortmund left-back blocks Khedira's cross well on the right-hand side as Madrid threatened.

24'

GREAT STRIKE FROM RONALDO!! Madrid's No. 7 hits the set piece very well but Weidenfeller is equal to it. The ball is swerving in the air as it flies towards the Dortmund goal but the home side's goalkeeper is well-positioned and able to parry Ronaldo's effort away.

23'

I WONDER WHO WILL TAKE THIS... A handball from Bender 35 yards from goal results in a free kick for the visitors.

22'

Hummels beats Ronaldo in the air to thwart a cross from the right but Gundogan soon loses the ball inside his own half to hand Madrid possession.

20'

Despite seeing more of the ball in the last few minutes Madrid are still yet to come close to testing Weidenfeller. To give you an indication of their play, Alonso has just pinged a pass into the stands. That does not happen very often!

19'

Madrid are starting to settle into their rhythm a bit after a difficult opening as Dortmund flew into an early lead. The Spaniards are moving the ball nicely in midfield, but their latest move breaks down as Gonzalo Higuain's cross to Ronaldo in the box is over hit.

17'

I've just seen another replay of that Dortmund goal and it really was an absurdly good cross from Gotze! Yes Lewandowski did well to lunge and reach it, but there was no way Madrid could stop it, it was weighted to perfection.

16'

Ronaldo lets his frustrations show as he catches Gundogan after the midfielder dispossessed him on the near side. Rightly, Dortmund have a free kick for the foul.

15'

STAT: Madrid's passing accuracy for the opening quarter of an hour is just 71 per cent. That is very low considering the players they have at their disposal!

14'

And Gotze's doing all that despite being booed by sections of the Westfalenstadion crowd whenever he touches the ball.

13'

Well, Gotze certainly isn't letting his impending transfer affect his game! The Germany international has been brilliant so far, mixing some skilful dribbling with some sublime passing, particularly his assist for Lewandowski's opener.

12'

The flag goes up for offside against Madrid on the right, just as they are appealing for a free kick after Bender had hurtled into Ronaldo. The visitors do not look too pleased with the referee after that decision!

11'

Madrid try and hit back immediately through Ronaldo but Xabi Alonso's pass to his Portuguese team mate is slightly too strong and runs all the way through to Roman Weidenfeller.

10'

STAT: The Bundesliga giants are the only unbeaten team in the competition.

8'

AssistMario Götze

8'

GoalRobert LewandowskiDORTMUND TAKE AN EARLY LEAD! LEWANDOWSKI IS THE SCORER! The Poland international connects with a superb cross from that man Gotze from the left to divert the ball past Lopez at the back post and give his side an early advantage. What a start for Klopp's side!

7'

GOOD STOP FROM LOPEZ!! The Madrid goalkeeper dives brilliantly to his right to claw out an effort from Marco Reus after the attacker had picked up the ball in the centre circle, driven at goal, and slid a shot towards the bottom left corner. The rebound fell to Lewandowski but he was unable to hit it first time and was eventually crowded out by Ramos and Pepe.

6'

A neat interception from Ramos steals possession for Madrid just as Dortmund looked poised to break into their penalty area, and the Spain international immediately starts an attack for his side down the right.

5'

One of Madrid's resident Germans, Sami Khedira, is adjuged to have fouled Gundogan and Dortmund now have a free kick on the halfway line.

4'

A great challenge from Bender wins the ball for Dortmund in the centre circle, but the home team's attack breaks down as Pepe throws his body in front of Lewandowski to deflect the ball away from the Madrid goal.

3'

It will be very interesting to see how Mourinho's side approach this game. They were outplayed in this very stadium back in October, while only a late Mesut Ozil free kick salvaged them a point in a 2-2 draw in November.

2'

Ronaldo gets an early touch of the ball on the left-hand side for the away side, but an uncharacteristic heavy touch takes it out of play, much to his disdain.

1'

Madrid get us underway over in Dortmund!

I WANT SCORE PREDICTIONS NOW! Send them to me on Twitter @charliefscott, or chuck them in the comments box to the right of my ramblings.

The teams are on their way out on to the pitch at the Westfalenstadion, and as expected Dortmund's Yellow Wall looks magnificent!

Gotze starts for Dortmund in the wake of the news that he is departing for pastures red in the summer, while Sven Bender and Ilkay Gundogan start in a midfield pivote for the Bundesliga giants. Klopp's side are boosted by the availability of Mats Hummels at centre-back, with Felipe Santana having deputised for the Germany international in the last round against Malaga.

SO... In comes Luka Modric for Angel Di Maria, as the Argentine makes do with a place on the bench after the birth of his first child on Monday. The rest of Madrid's XI is as predicted, with Sergio Ramos at right-back in place of the suspended Alvaro Arbeloa.

So, you've had my exciting preamble, how about the starting XIs? Mourinho told the press yesterday who he would play tonight, but I for one am predicting at least one change from the XI he gave to journalists. We all know what he is like.

The timing of the Gotze announcement could not be worse. Just hours before the club's biggest game in 15 years! That has got to hurt. In Spain I imagine they would be nursing their cojones.

Meanwhile, something is rotten in the state of Dortmund. On Tuesday it was announced that one of the stars of their season, Mario Gotze, will be packing his bags and moving to their Bundesliga rivals - and fellow Champions League semi-finalists - Bayern Munich for €37m. AND, if that was not bad enough, reports emanating in the build-up to the game today suggest that Robert Lewandowski will also be making the switch from the Westfalenstadion to the Allianz Arena.

For starters Michael Essien is unlikely to start at left-back, with Fabio Coentrao fully fit, while los Blancos also have a 'happy' Cristiano Ronaldo in attack. And in defence Raphael Varane has emerged as one of the continent's most exciting prospects over the course of the past six months.

The two sides have faced one another twice in the group stages of this year's competition, with Dortmund winning at home and the other game in Madrid ending as a draw. Yet things have certainly changed since Jose Mourinho's team lost that Group D fixture in October.

It really is difficult to know which angle to approach this game from! I'm going to plump for a look at their recent meetings...
